Special Features

ZK-502M AMP --- Mini Bluetooth AMP,its peak output power can reach 50W+50W, wide voltage input: 5-24V,suitable for speakers 10-100W, 4-8Ohm
EASY CONNECTION --- This AMP has three input methods, their input sequence is USB mode/AUX mode/Bluetooth mode.
TWOWAY TO USES --- When you connect passive speakers, this AMP is a Bluetooth power amplifier; when you connect active speakers, this AMP is equivalent to a Bluetooth receiver. (It should be noted that two types of speakers cannot be connected at the same time)
HIGH PERFORMANCE --- Overheating, overcurrent, short circuit protection mechanism,Equipped with 18x20x10mm heat sink, left and right two-channel stereo, Bluetooth version 5.0, the actual transmission distance is 15 meters, in the case of no obstruction, the U disk file system must be FAT32, the maximum support 32GB
NOTICE --- adequate output power is required when the audio input is sufficient and the power supply voltage/current is sufficient, the relative power will be higher. Different impedance horns will have different output power.In the case of sufficient voltage and current, the larger the impedance horn, the smaller the relative sound power, please pay attention!
